BEARING FOB HIGH-SPEED FLIERS.

Specification of Letters Patent.

Application filed July 12, 1920. Serial-No. 395,719.

To all whom it may concern.

Be it known that I, HARRY zen of Great Britain, residing at Methuen, in the county of, Essex and State of Massachusetts, have invented certain new and useful Improvements in Bearings for High- Speed Fliers, of which the following is a specification. f

This invention relates to bearings for textile machines or frames for spinning-roving,

of what are known as the flier types It isapplicable specifically to certain" types of fliers, and its purpose is to provide means whereby a higher speed can be obtained, and therefore greater production, without injury to the machine.

V In the type of machines to which my device is especially applicable, there are a plurality, generally a large number,, of spindles each carried near its bottom in suitable bearings 1n the frame and connected by suitable belts or cords, so that the spindles can be revolved at high speed. The flier consists of two arms connected together and terminating in a tubular neck, which .is slipped over the top end of a spindle in such manner that it will be carried thereby and will revolve therewith. 1

I am well aware that in certain types of Gill boxes and drawing boxes, the top end of the spindle is carried in closed bearings,

but with such bearings the process of dofling is slow, and the use of such bearings has been found impractical. on flier frames,-

where there are a large number of spindles, as, for instance, from 2 to 200' on each a V My device is peculiarly useful in connection with what is known as the Dandy rover, where the delivery point of the delivery rolls is directly over the'top of the spindle VI and the center of the tubular neck of the flier,- and in flier spinning frames, where the rolls are not directly over the spindle but where, as now in use, what is known as a fly M board carrying guide eyes each of which isdirecly over the, center of the SPlIldlQ, 1s

used. 7

I I have discovered that by making the neck of the flier of such form and of such length v on the outside that it can be guided or steadiedby a bearing open at the.- front or the side, the speed can be greatly increased and the production also increased. On new flier s, the neck can be made of suitable SLATER, a citi- Patented Mar, 1, 1921'. 7

length and shape, and. on old flie'rs I can preferably, simultaneously, as these parts are not locked together in any way.

In the construction where I move-the bear- 1 ings away from the fliers, I find that, by a slight modification of the bearings, the fly board can'be dispensed with.

My invention consists. primarily in so forming the neck of a flier,;as distinguished from a spindle, that it can be'guided by a bearing open at the front side or at another side, such neck and bearing being so arranged that they can be separated in a substantially horizgontal direction.

In the draw ngs, Figure 1 is .ancelevatio'n partly in sectlon showlng a single spindle and flier ofaframe for working textiles of" the Dandy rover flier type, "wherein the top of the spindle and flier can be swung out; in a well known manner. 3 i Fig. 2 is a view similar to Fig. --1:o-f a single spindle and flier of..an0ther type of frame, wherein the spindle is'revoluble but does not swingout. v H p Fig. 8 is an enlarged plan View of. the top of a flier and bearing embodying my invention, as shown in Figs. 1 and 4; v

frame, such bearings being supported by the rail 8 carried by rollers, such as 11, which run on tracks, such as 9, in a Well known manner. The whirl, such as 13, intermediate rail 12, the lifter rail 1 1 and the spool Each spindle carries at the top a flier F for the roving R which is delivered by rollers 33 and 34:. The spindles, spools, and fliers are all arranged so that they can betipped, thus swinging the necks 22 as well as the arms 20 and 21 of the fliers outward in a substantially horizontal direction.

As shown in Fig. 4, the top'end of each spindle S- is slotted at 16 to embrace a pin, such as 23, passed through the neck 22 of the flier. Each neckhas roving eyes 24 and 25 which preferably are elongated as shown. I also prefer to insert at the top a smaller roving eye 26 to keep the roving in the center- .1

In making over old fliers, I prefer to sweat or drive on to neck 22 atubular thimble, such as E, having at the bottom a rounded skirt forming an annular channel 31 which will catch and retain any excess of oil. The outside of this tubular thimble E is true andcylindrical, adapted to revolve at high speedwith the spindle and flier.

To cooperate with the neck of the flier carried by a spindle of this type, I prefer to use fixed bearings H open at the front 43 to al low the neck or the thimble E to slip. in and to be guided thereby. As shown, for each spindle I attach a bracket K, which has adownwardly projecting arm 53, by means of a cap-screw 55 passingthrough enlarged slot 54 to the rail C. This bracket K has a horizontal arm 50 and an adjusting slot 51 through which, and through slot 47, in a corresponding'arm 48 of a bearing H, a bolt, I

such as 52, passes. Therefore the bearing H is adjustable vertically and horizontally.

Referring to Fig. 3, the bearing IIvis enlarged intoa head in'which is a slot 40 which is preferably slightly tapering to receive the bearing member 11, which may be of bronze or any other suitable anti-friction material, rounded at the back 42 to fit snugly on the neck or thimble of the flier, and open at the front 43 whereby it can be swung out without removing any bolts or latches. I

prefer to arrange an oil well 44 in the head.

of the bearing, and to bore a small oil hole 45 therefrom so as to reach the neck or thimble, and preferably'in this I insert a wick 46 to carry the-oil graduallybetween the hearing surfaces.

'In the construction shown in Fig, 2, B

represents the frame of a flier spinning capable of being moved back away from them in a substantially horizontal direction. To accomplish thisI prefer to arrange these hearings 1n sections of six or eight,"as

indicated in Fig. 6. For each section, I provide two brackets L, L, one at each end, fixed to the rail C as by screws 59 and each having bearing 60 for an operating shaft 61 which may extend the entire width'of the machine. This shaft can be operatedby a handle 127 shown in Fig. 6, and, for each section, carries near each end thereof a gear 62. Each bracket L hasan upward extension 63 with a passage 64 which serves as a bearing for a carrier arm 70 having rack teeth 71 at the bottom, each set of teethengaging a gear 62.

Bolted to the top of each pair of toothed carrier arms is a bearing carrier rail 65, and to this are adjustably bolted the open front side bearings M. Each such bearing is open at the front73 and shaped at the back to guide the tubular neck or thimble,- such as E, of a flier. It will be readily seen that, by turning the handle. 127, the various gears 62 operating on racks 71 of carrier arms 70 will move the bearing rails 65 and the bearings M carried thereby back and forth so that when it is desired to doff, they can all be moved back out of the way, as indicated by the dotcd lines in Figs. 5 and 6.

I find that I can dispense with thefly board generally used to direct the yarn from the delivery rolls to a point directly over the spindles by'making the head 66-of each bearing M extend upwardly and over, and inserting in the top thereof, directly over the center of the spindle when the bearing is in position, an open sided eye, such as 68, which may be of porcelain if desired. The upper part of the top ofthe head is open at 67 sothat the bearings can be moved back or for-- ward without breaking the arn. In order to lock the parts in place may. use a set screw shown at 76. r

shown in Fig. 5, I may, as shown in Fig. 7 use carrier arms 80, each havlng two de- 12'0 Instead of using a" rack and gear, as

pending legs 81 and .82between which is an eccentric 83 mounted on shaft 61.

In Fig. 8, I show a-flier F made with neck 90 which extends upwardly at 91 a greater distance than is customary in" such cases, having roving eyes 95, oil skirt 93, and" rounded'bottom"92, together with a top eye 94. It is obvious that whether a thiinble, which may be in the nature of a bushing,

such as E, is used, or a neck suitably made. in the first place, as shown in Fig. 8, the:

is engaged and disengaged from theflier neck. 7

It is evident that whether a thimble is used on the neck or the neck is so formedas to serve the same purpose, the principle is the same, and it is evident that whether the opening in my bearing is at the front side, the right side, or the left side, the principle is the same. As the pull of the bands on the whirls is from the back, I prefer to have the open part of the bearing on the ing textiles, of a vertical spindle carried front side, however.

The type of spindle in connection with which I use my invention is that wherein the top is free to receive a flier, the bearings being near the bottom end of the spindle. -When I speak of the flier or flierneck and bearings being horizontally separable, I include any slight curve, such as that which the flier neck takes at the start, as shown in Fig. 1, or the bearing takes, as shown in Fig. 9. I

I claim: 7
